I connected your code into a program that I'd written around Erel's Eval routine. Your code breathes new life into it. Allowing the user to select a range of x values & uses your routines to populate a table based on the formula entered into a text box. The user can then display the table in one of 3 graph formats. Thanks again for the work you did in creating the expression calculator. I only needed to change one thing & that was to reset the 'C' variable after a calculation so that it would accept modified variables thereafter.
Cheers!!

Hallo Filippo,
Here you are, added SQRT and LOG.
There are some strange behaviours, also in version 2.1, I haven't yet looked in detail on what happens.
Best regards.
I have your program expanded and the error "Undefined variable" fixed.Two examples of what I called 'strange behaviours'.
If you enter ABS(-2) and execute it, you get twice the error message 'Undefined Variable', but the program does the calculation.
